I am a Senior Research Scientist at Wright State Research Institute in Beavercreek, OH and Director of Collaboration and Cognition Laboratory. Previous to this appointment, I was a research scientist at the University of Maryland Institute for Advanced Computer Studies (UMIACS) at College Park, MD. I have also served as a Program Manager in the Information Innovation Office at DARPA, as a Senior Computer Scientist at Raytheon BBN Technologies, Cambridge, MA, and as an Assistant Professor in the Department of Computer Science and Engineering at Wright State University in Dayton, OH
I have broad research interests in artificial intelligence and cognitive systems with respect to high-level reasoning in humans and machines. Technical areas include goal-driven autonomy, volitional explanation, multistrategy learning, case-based reasoning, story understanding, mixed-initiative planning, and computational introspection/metareasoning. In particular, I am interested in how deliberative goals affect behavior across all of these processes. Forall cognitive mechanisms, I seek to understand how goals arise and howthey change over time.
